Hov had an interview with Power 105.1 previously where he said sports agents had gotten lazy. "They get an artist, right, however they acquire the artist—I mean the athlete—they get them and they knock on the same doors," said Hov. "They go to Nike, they do the contract and they sit back. So they've been sitting around for 20, 30 years just not doing anything. So me coming in, that's a problem for them. Now they have to go to work."

In response, Boras suggested that Jay Z's sentiment proved he doesn't know the agency game. "Anyone who thinks playing the game of baseball is like being an artist knows nothing about the game of baseball," Boras said. "I don't worry about others, because you know what, in the end, as always, there are few survivors in [the agency] game. This game is something that when you come, and you look, and you don't see—when you don't see, you're not here long."

Boras further explained his stance. "The reality of it is those deals have shrunk," he said. "The executives of companies want more time from the player. They want him to get up at 7 a.m. and do an ad after arriving home at 3 o'clock in the morning? I don't want a player doing that. I want him at the field at 3 p.m. and rested."

The longtime agent also made a quip about Jay Z's professionalism. "When your agent wears a Yankee hat," he said, "how seriously are they going to take you?"
